Definitions

  • This invention is a special tool for removing and installing fuses in the valves of the automotive engine's cylinder head.
  • This special tool for removing and installing fuses in the valves of the automotive engine's cylinder head refers to the technique of removing and installing fuses in the automotive engine valves and it is comprised by a lever pressure of the valve springs forming the motor vehicle's engine cylinder head, which slides on a steel horizontal shaft.
  • the said shaft is lying an vertical columns which brace on two metal bases, firmly adapted to the backets of the engine's cylinder head; the said lever bears a head socket for the end unions which aid to the removal of the valve fuses from the motor vehicle engine's cylinder head and hence their placing during the works for the engine repair.
  • This technique is used in different types of motor vehicle engines with a convenient adaptation of the fastening bases.
  • the current patent application aims to provide safe, quick and efficient job, during the motor vehicle engine repair and especially during the repair of the valves in the cylinder head avoiding thus the risks of valve loss or valve failure.
  • Figure 1 shows the top view of the current patent application which is put on the thread backets of the cylinder head and depicts the lever compression (22), sliding on the horizontal shaft.
  • the said shaft is assembled with the screws (4) on the columns (2) and bears the head (25) with the thread of the end unions' socket (26) along with the bases (1) with the apertures (24) of the fastening screws in the thread backets of the motor vehicle's engine cylinder head.
  • Figure 2 presents the oblique view of the bar pressure (22) fastening itself on the shaft (3) and the notch (23) for its induction in the shaft.
  • Figure 3 shows the top view of the fastening bases (1) with the apertures (24) corresponding to the thread backets of the cylinder head where the fastening screws are adjusted.
  • Figure 4 shows the front view and Figure 5 shows the top view of the special end union which removes the valve fuses from the motor vehicle's engine cylindrical head.
  • the said end union possesses a thread (9) screwed on the head (25) of the level pressure a circular magnet (11) with the bond chamber of the fuses (12) and the circular centering guide of the valve (13).
  • Figure 6 shows the front view
  • Fig. 7 shows the top view of the special end union which inducts the fuse valves in the cylinder head of the motor vehicle engine bearing a thread (16) screwed to the head (25) with the balls (18), fastening the fuses (21), forced by a spring ring (19) on the fuse shaft handle (14) guide with the valve spring compression during its induction (17) to the centering guide (20) and the sample fuses (21).
  • the tool for removing and replacing fuses in the valves of the motor vehicle's engine cylinder head can be operated if the bases (1) Fig. 1,2,3 are put on the thread backets of the camshafts with their screw fasteners.
